目的探讨具有前房角狭窄的患者白内障摘除术后的前房角改变及其眼压的变化。方法在具有前房角狭窄的35眼白内障患者中,术前及术后均用前房角镜检查前房角,记录镜象,并测量和记录眼压。结果术后W(wide-angle)25眼,其中4/4周W18眼,3/4周W7眼,N(narrow-angle)I～NⅡ10眼,与术前相比有显著差异(x2=68.00,P<0.001);术前入口<10°者25眼,≥10°～≤20°者10眼,术后>200者35眼,与术前相比有显著差异(x2=70.00,P<0.001);小梁色素1级15眼,占42.9%;术前眼压16mmHg～20mmHg28眼,术后为8眼,与术前相比有显著差异(x2=6.123,P<0.05)。结论具有窄房角的白内障患者,晶状体摘除术后的前房角重新开放,可有效的降低眼压,对防止因房角关闭引起的青光眼有预防和治疗的作用。
Objective To investigate the changes of anterior chamber angle and its intraocular pressure after cataract extraction in patients with stenosed anterior chamber angle. Methods In 35 eyes of cataract patients with stenosed anterior chamber angle, the anterior chamber angles were examined with gonioscopy before operation and after operation, the images were recorded and the intraocular pressure was measured and recorded. Results There were 25 eyes with wide-angle W 4, 4 weeks W 18, 3/4 weeks W 7 and N (narrow-angle) I ~ N II 10 eyes, which were significantly different from preoperative , P <0.001). There were 25 eyes of less than 10 ° before operation, 10 eyes of ≥10 ° ~ ≤20 ° and 35 eyes of more than 200 after operation, which were significantly different from those before operation (x2 = 70.00, P < 0.001). Trabecular pigment grade 1 was 15 eyes (42.9%). Preoperative intraocular pressure was 16mmHg ~ 20mmHg28 eyes, and postoperative was 8 eyes. There was significant difference (x2 = 6.123, P <0.05). Conclusion The cataract patients with narrow anterior chamber angle after cataract extraction can reopen the anterior chamber angle, which can effectively reduce the intraocular pressure and prevent and cure the glaucoma caused by the closure of the angle chamber.
